Cool City focuses on the metropolitan area of Naples. It aims at the recovery of dispersed and no-longer-used water to mitigate the rise in temperature at a city level.

Cool City aims at the improvement and re-functionalization of the abundant spring waters that have characterized the hydrogeological history of the Neapolitan city and that today are channeled into sewers or spills connected to the sea. In this regard, Cool City brings together expertise in the fields of urban design, air pollution, hydraulic systems, air conditioning systems, environmental engineering, biology, urban sociology, archeology and geology.
